When a user adds a LINE account as a friend, their LINE UID is registered in Marketing Cloud. At this time, a random GUID format is automatically assigned as the Contact Key. To link this LINE UID to an existing Contact Key already registered in Marketing Cloud, you must perform an import using the following steps. Once the import is complete, the specified Contact Key and LINE UID will be linked.
1.Prepare a CSV file with the following structure.
Example CSV file:
----
AddressID,ContactKey,ChannelID,DisplayName
Ue6a4c0328bf8e580ac597XXXXXXXXX,[ContactKey],[ChannelID],[DisplayName]
----
Replace each placeholder with your actual data.
・Specify the LINE UID in "AddressID".
・Specify the existing Contact Key you want to link in "ContactKey".
・Specify the target LINE Channel ID in "ChannelID".
・Specify the LINE user's display name in "DisplayName". If there is no display name, you can enter any text; this will not affect message delivery.
・In addition to the required fields (AddressID, ContactKey, ChannelID), you must include at least one of the following fields for the import: DisplayName, PictureURL, or StatusMessage.
